Orangettecoleman (great name!), Goosala and others-- 12oz is not HEAVY. Unstrung that is about 336g or so, maybe a bit more. If we keep changing the definition, soon it will be the "medium mass player's club"... So get busy with some lead tape, boys. Once you adjust, you'll be glad ya' did.

PS I have a friend who is a Sports Trainer who used to work on Tennis Players down in LA in the late 80s and practiced with a few pros as well, including Jim Pugh, Pam Teegarden and Brian Teacher (who won the Australian Open in 1980). Teacher's Kennex Black Ace weighed 19.5oz. That's right--- 19.5. AND he played serve and volley tennis with it. Now THAT is HEAVY.

How do you even make a racket that heavy? That's about a month of minimum wage of lead tape...
